Does one pinch of chewing tobacco have more nicotine than one cigarette?

Depends on how much dip you're throwing in your mouth obviously, but a cigarette typically contains 1-1.5mg of niccotine. Dip contains anywhere from 4-25mg of niccotine per gram of chewing tobacco (a can contains 34g of dip). (34g/Number of pinches per can) x (4 to 25mg of niccotine) gives a rough estimate, but yes a typicall pinch of chewing tobacco contains much more niccotine than a single cigarette.
